ICSE Class 9 Physics: Syllabus, Topics & Sample Practice

Measurement, Motion & Forces

• Ch 1 Measurements and Experimentation

  International System of Units and the required SI units with symbols; measurements using Vernier callipers and the micrometre screw gauge; least count and zero error; the simple pendulum and its time period.

• Ch 2 Motion in One Dimension

  Scalar and vector quantities; distance, speed, velocity and acceleration; distance–time and velocity–time graphs; and the equations of uniformly accelerated motion (v = u + at, S = ut + ½at², v² = u² + 2aS).

• Ch 3 Laws of Motion

  Contact and non-contact forces; Newton's first, second (F = ma) and third laws of motion; linear momentum; and gravitation — the universal law, acceleration due to gravity, and the distinction between mass and weight.

• Ch 4 Fluids

  Change of pressure with depth (p = hρg), transmission of pressure in liquids and atmospheric pressure; and buoyancy, Archimedes' principle, relative density and the principle of floatation.

Heat & Energy

• Ch 5 Heat and Energy

  Heat and temperature and heat as a form of energy (SI unit the joule); the anomalous expansion of water; energy flow and its importance; renewable and non-renewable energy sources; and the greenhouse effect and global warming.

Waves — Light & Sound

• Ch 6 Light

  Reflection of light and images formed by a pair of parallel and perpendicular plane mirrors; and spherical mirrors — concave and convex — with ray diagrams, the mirror formula f = R/2 and sign convention.

• Ch 7 Sound

  The nature of sound waves and the need for a medium; propagation and speed in different media (V = fλ); infrasonic, sonic and ultrasonic frequencies and their applications; and loudness, pitch and quality of sound.

Electricity & Magnetism

• Ch 8 Electricity and Magnetism

  The simple electric circuit, electric current and its relation to charge, conductors and insulators, and potential difference (V = W/q); and induced magnetism, the magnetic field of the earth, neutral points and the electromagnet with its uses.

Point to the Method

Names the tool to reach for (e.g. "Use an equation of motion") without giving the answer.

Guided Reasoning Prompt

Prompts the key step (e.g. "What is the initial velocity when a body starts from rest?").

Complete Worked Solution

Shows the full step-by-step working and explains why the answer is correct.

Master Units and Least Count Early

Get comfortable with SI units, Vernier callipers and the screw gauge now — clean measurement skills underpin every numerical you meet later.

Practise Numericals Step by Step

Write out what you know, pick the right formula, then substitute — the paper rewards clear method, not just the final number.

Keep a Tidy Practical File

Internal assessment is 20 marks; neat, well-labelled experiments and observations genuinely lift the overall grade.

What are the main topics in ICSE Class 9 Physics?

The CISCE Class 9 syllabus is organised into eight sections: Measurements & Experimentation; Motion in One Dimension; Laws of Motion; Fluids; Heat and Energy; Light; Sound; and Electricity and Magnetism. Always confirm the current syllabus with CISCE or your school.

How is ICSE Class 9 Physics assessed?

By one 2-hour written theory paper of 80 marks, plus 20 marks of internal assessment for practical work (experiments and a practical file) — totalling 100.

Is Class 9 Physics a separate paper in ICSE?

Yes. Within the Science group, Physics is examined as its own paper, separate from Chemistry and Biology, each with its own 80 + 20 scheme.

How does Class 9 Physics connect to the Class 10 board exam?

ICSE Physics is a two-year course assessed at the end of Class 10. Class 9 lays the foundations — measurement, motion, forces, heat, light, sound and electricity — that are developed and examined in the Class 10 board paper.
